What does entanglement actually mean?

So in this episode we’re going to be trying to get our heads around one of the most extraordinary phenomena ever recorded in subatomic physics: Quantum Entanglement. Famously dismissed by Einstein as ‘Spooky action at a distance’, it has been proved to exist in the lab over and over again since then. This non-local phenomenon is when sub-atomic particles remain connected so that the physical properties of one will affect the other, no matter what the distance is between them. It’s been in the news a lot recently not only because it has been photographed by a team at the University of Glasgow, but also because of a host of successful so called ‘Teleportation’ experiments, in which entanglement has been used to send information instantaneously between two computer chips that have no causal connection between them whatsoever. I believe the implications of this non-local phenomenon are among the most important scientific discoveries of our time, most importantly to update our purely classical ‘cause-and-effect’ understanding of the world. But it also begs the question, through what medium is that information passing between those two entangled particles, if not through Space and over time?

To help us get our heads around this mind-bending reality is theoretical Physicist Dr Chris Fields, an independent scientist interested in both the physics and the cognitive neuroscience underlying that human perception of matter in space and time.

Chris began his career as an experimental physicist, obtained his Ph.D. in Philosophy of Science at the University of Colorado and was an early developer of automated DNA sequence analysis tools at the Human Genome Project. He has published over 130 peer reviewed papers in nuclear physics, artificial intelligence, molecular biology and cognitive psychology.
